okay, so I’ve had this random thought. We have all been told that objects fall to the ground at the same speed, even if they have different masses. While it’s true that any two objects, regardless of mass, will accelerate towards Earth at the same speed, that doesn’t mean the Earth is accelerated towards the object at the same speed. Heavier objects have a higher gravitational force, and because of Newton’s Third Law, the Earth expirences the same force towards the object. Because Earth will accelerate towards heavier objects faster, heavier objects dropped in a perfect vacuum will hit the ground before a lighter one.
